Description
Technical field
The utility model relates to 2.5 megawatt wind units resilient support.
Background technique
With the deep expansion of global energy-saving and emission-reduction, various countries also constantly accelerate the paces that new energy development utilizes.Wind-powered electricity generation
Construction, especially offshore wind farm, oneself becomes the focus in the whole world, and various countries are also growing day by day to the manufacture enthusiasm of offshore wind turbine.
Offshore wind turbine is different from land wind power generating set, it is in existing land foundation of wind-driven generator unit
It is upper to be directed to what offshore wind speed environment progress adaptability " ocean " grew up.In order to bear marine high wind load, seawater
Corrosion and wave stroke etc., structure is complicated more than land for the basis of offshore wind farm unit, and technical difficulty is big, high construction cost.
Oversea wind power generation starting in China's is limited to technology, the deficiency of research and development, the above offshore wind turbine master of MW class than later
Components are wanted still to still rely on external import, domestic enterprise can not also extensive autonomous production.Wind power equipment manufacturing industry is wind
The core of electric industry, with the development of domestic Oversea wind power generation, the above offshore wind turbine master of the MW class of high quality
Wanting components, supply falls short of demand, production domesticization, the large-scale production of the present above offshore wind turbine main parts size of MW class
Shortage, have become restrict Oversea wind power generation development bottleneck.
In order to reduce the resonance problem of components and generator, resilient support is widely used at present, but its effect is general, and
It can not adjust, and can only generally solve the vibration in a direction.
Utility model content
The purpose of this utility model is that overcoming defect existing in the prior art, 2.5 megawatt wind unit elasticity are provided
Support, damping effect is obvious, and can adjust in use for some time.
To achieve the above object, the technical solution of the utility model is design 2.5 megawatt wind units resilient support, including
Upper support and lower support, it is upper to support and be respectively provided with threaded hole in lower support, it is adapted to threaded hole and is equipped with screw rod, upper support and lower branch
Support is fixedly connected by screw rod, and the length of screw rod is greater than the sum of the height of upper support and lower support, and screw rod exceeds the portion of upper support
Divide and the part beyond lower support is fixedly installed nut respectively, upper support is to be equipped with the first semicolumn bodily form slot in the middle part of lower end
Cuboid, the first semicolumn bodily form slot run through upper support, and lower support is that upper center is equipped with the rectangular of the second semicolumn bodily form slot
Body, the second semicolumn bodily form slot run through lower support, and the first semicolumn bodily form slot and the second semicolumn bodily form slot cooperatively form circular hole,
The length and width of the tubular elastomer of setting in circular hole, upper support and lower support are equal, and the diameter of circular hole is less than upper support
Width, screw rod are located at the side of circular hole.This resilient support plays certain damping effect in addition to the upper support and lower support of itself,
Elastomer is set in the circular hole also formed between upper support and lower support, enhances the damping property of this resilient support in this way, and
And since spiro rod length is longer, can be realized again by adjusting nut when continuing to resonate in use for some time
Adjustment, so that the damping timeliness that the spacing between supporting up and down as the abrasion of elastomer is gradually turned down, is flexibly supported with extension.
Further technical solution is that upper support and the setting of lower support level, screw rod are vertically arranged, upper support and lower support
Several threaded holes are equipped with, screw rod quantity is consistent with the screw thread hole number of upper support.
Further technical solution is that upper padding plate is arranged in lower its lower end of support, and the spiral shell being adapted to screw rod is arranged on upper padding plate
Pit, upper padding plate are fixedly connected by several elastic cylinders with lower bolster, and the transverse direction that is vertically arranged, having that elastic cylinder has is set
It sets, the threaded hole being adapted to screw rod is set on lower bolster.The elastic cylinder of damping, and bullet are capable of in setting again in this way under lower support
Property cylinder have transverse direction, have vertical, can both maximize reduce blower vertical vibration in use in this way, moreover it is possible to
Reduce lateral vibration, the resonance of both direction can be reduced, damping effect is better than conventional resilient support.
Further technical solution is that upper padding plate is arranged in lower its lower end of support, and the spiral shell being adapted to screw rod is arranged on upper padding plate
Pit, upper padding plate are fixedly connected by several elastomers with lower bolster, and elastomer is in spherical, setting and screw rod on lower bolster
The threaded hole of adaptation.Then which direction the direction of pipe resonance or vibration is not to spherical elastomer, can damping.
Advantages and beneficial effects of the utility model lie in that resilient support plays one in addition to the upper support and lower support of itself
Also elastomer is arranged in the circular hole that is formed between upper support and lower support in fixed damping effect, enhances this elasticity in this way and props up
The damping property of support, and since spiro rod length is longer, in use for some time can be by adjusting when continuing to resonate
Nut is readjusted to realize, so that the spacing between upper and lower support is gradually turned down with the abrasion of elastomer, to extend elasticity
The damping timeliness of support.Damping effect is obvious, and can adjust in use for some time；Setting being capable of damping again under lower support
Elastic cylinder, and elastic cylinder have transverse direction, have vertical, in this way can both maximize and to reduce blower in use
Vertical vibration, moreover it is possible to reduce lateral vibration, the resonance of both direction can be reduced, damping effect is than conventional elasticity branch
It supports.Then which direction the direction of pipe resonance or vibration is not to spherical elastomer, can damping.
